ANNEXE No. I & II
NOTES ON THE RECEPTION OF PERSONNEL AND STORES BY AIR.
1. MAP REFERENCES FOR RECEPTION (OR ANY OTHER) POINTS.
a.
If possible use the DUTCH MILITARY MAP 1:50.000, each sheet of which bears a number. Each sheet is cross-lined with 40 vertical lines numbered from 00 to 40 and 25 horizontal lines numbered from 50 to 75, the distance between two lines being 1 km. To obtain the map reference, first take the number of the vertical line to the West of the point and add the estimated distance from the line in tenths of a km - each 2mm is 1/10 of a km. Then take the number of the horizontal line to the south of the point and, once again, add the estimated distance from the line to the point in tenths of a km. In this way a six-figure map reference is reached.
b.
If the first mentioned map cannot be procured, use the ANWB AUTOKAART VAN NEDERLAND, 1:200.000. This has three sheets; each sheet has reference numbers going from west to east and running into three figures, and other numbers going north to south and running into two figures only.
Three figures must always be given for the west-east reference; thus, for example, 2 is shown as 002; 20 as 020; 59 as 059. Similarly, two figures must always be given for the north-south reference.
A reference on this map, coorrect within about 1 km, therefore consists of five figures only. Map reference of dropping points will be supported in every cade by the bearing and distance from two readily distinguishable landmarks or churchesof towns near the point. This is essential in order to locate the exact position of the point.
Remember to specify which sheet is in question.
c.
If circumstances oblige you to work off some quite different map, you must tell us which maps you are using, scale, sheet and the date of issue.
RECEPTION POINTS.
The places selected must be at least 300 metres square and reasonably easy to locate from the air at night. Rivers, canals, lakes and straight streches of roads are good landmarks.A railway is not, as a rule, a good landmark. Keep at least 200 metres away from woods or lines of tall trees.
RECEPTION COMMITTEE.
This should consist of four persons per container expected, but proportion may be reduced if the number of containers is large. Experience will show whether, for instance, fifteen man can dispose rapidly of six containers, their load and their parachute.
Holes or suitable hiding places must be prepared in advance for the speedy disposal of containers and parachutes.
THE ACTUAL RECEPTION.
Air operations have often failed owing to lack of adequate ground lights. These lights must be as strong as possible and clearly visible up to a height of 600 metres. They should have an arc of 60 degrees.
The dropping area should be marked by two red torches and one white one arranged as in the diagram below. One additional white torch (flashing the agreed recognition letter), should be placed at the down wind end of the line so as to indicate to the aircraft the direction of the wind.

white light flashing agreed recognition letter.
On hearing the approaching aircraft, the lights should be switched on and your recognition letter should be flashed continuesly until you see the aircraft has started to drop its load. The torches should be held a arm's length and pointed towards the aircraft throughout the operation until it has been completed. It is essential that the pilot should be able to see the lights the whole time, especially when he has once been over and is circling in order to make his run up.
On seeing the lighting system, de aircraft will approach flying up-wind and will release the load when approximately over the last red torch. The wind will cause the load to drift back to the field.
Before extinguishing your lights make sure you have your complete load as, if the aircraft is carrying a large load, it may make two run-ups.
